GStreamer-WARNING **: External plugin loader failed.

[Brilliantov Kirill Vladimirovich]

Hello!
I use glib-2.24.2 and gstreamer-0.10.36 on board with iMX538 CPU.
I build gst-rtsp-0.10.7 and copy libgstrtspserver-0.10.so.0.0.0 to 
/usr/lib/gstreamer-0.10 on board, after this I create symbolic links on it.
But when I run gst-inspect I get follow error:
# ./gst-inspect | grep rtsp

(gst-inspect-0.10:1213): GStreamer-WARNING **: External plugin loader 
failed. This most likely means that the plugin loader helper binary was 
not found or could not be run.
rtsp:  rtspsrc: RTSP packet receiver
rtsp:  rtpdec: RTP Decoder
realmedia:  rtspreal: RealMedia RTSP Extension
asf:  rtspwms: WMS RTSP Extension

I try create symbolic links on library in /usr/lib, but this not solve 
problem.

How can I solve this problem?
Thank you and excuse me for my bad english.
